On Sunday, a piece of metal with a handle on it was found on Reunion Island. According to Sky News, "It had Chinese and Malaysian writing on it and was thought to be from the inside of an aircraft."

But reports the debris came from a plane haven't been confirmed, and Malaysian officials have cast doubt on the object's origin, according to the BBC.

"As you can imagine, as the days go past, there's more and more interest in people combing this area trying to find something that may give further clues to what happened to that plane," Karen Allen reported for the BBC.

And NBC points out some debris could have taken a different path in the currents.

"And finding anything relevant amid all this junk will be hard," Bill Neely reported for NBC.

This comes less than a week after a piece of a wing was found on the French territory east of Madagascar.

Now, the National Highway Traffic Safety Administration is investigating the company that makes the hackable infotainment system.

That company is Harman Kardon, which makes home and auto audio equipment. The company has its audio systems in several major vehicle brands, and according to the NHTSA, there could be more than 2.8 million infotainment systems affected.

The NHTSA says it's opening the investigation to determine "if there is cause for concern that security issues exist in other Harman Kardon products."

Meanwhile, Fiat Chrysler has issued a 1.4 million-vehicle recall and added security to its cellular network to prevent hackers from compromising more vehicles through the infotainment system.
